The microbiota impedes pathogen invasion of the intestinal ecosystem, a phenomenon termed colonization resistance. In an upcoming issue of Cell, Stacy et al. describe host-initiated metabolite pathways that functionally alter the microbiota after primary infection, thereby augmenting colonization resistance to subsequent infection.

微生物记忆

微生物群阻碍病原体入侵肠道生态系统，这种现象称为定植抗性。在即将发行的Cell 中，Stacy 等人。描述宿主启动的代谢物途径，在初次感染后功能性改变微生物群，从而增强对后续感染的定植抵抗力。
